A charge-driven feedback loop in the resonance fluorescence of a single quantum dot
B. Merkel, A. Kurzmann, J. -H. Schulze +3
Semiconductor quantum dots can emit antibunched, single photons on demand with narrow linewidths. However, the observed linewidths are broader than lifetime measurements predict, d…
Optical blocking of electron tunneling into a single self-assembled quantum dot
A. Kurzmann, B. Merkel, P. A. Labud +4
Time-resolved resonance fluorescence (RF) is used to analyse electron tunneling between a single self-assembled quantum dot (QD) and an electron reservoir. In equilibrium, the RF i…
Asymmetry of charge relaxation times in quantum dots: The influence of degeneracy
Andreas Beckel, Annika Kurzmann, Martin Geller +4
Using time-resolved transconductance spectroscopy, we study the tunneling dynamics between a two-dimensional electron gas (2DEG) and self-assembled quantum dots (QDs), embedded in…
A quantum Hall Mach-Zehnder interferometer far beyond the equilibrium
E. V. Deviatov, A. Ganczarczyk, A. Lorke +2
We experimentally realize quantum Hall Mach-Zehnder interferometer which operates far beyond the equilibrium. The operation of the interferometer is based on allowed intra-edge ela…
Transverse rectification in density-modulated two-dimensional electron gases
A. Ganczarczyk, S. Rojek, A. Quindeau +7
We demonstrate tunable transverse rectification in a density-modulated two-dimensional electron gas (2DEG). The density modulation is induced by two surface gates, running in paral…
Equilibration between edge states in the fractional quantum Hall effect regime at high imbalances
E. V. Deviatov, A. A. Kapustin, V. T. Dolgopolov +3
We experimentally study equilibration between edge states, co-propagating at the edge of the fractional quantum Hall liquid, at high initial imbalances. We find an anomalous increa…
